The PSTN and ISDN Switch-Off: Is Your Business Ready?

The way Irish businesses make phone calls is changing permanently. The traditional copper-wire networks we have relied on for decades—PSTN and ISDN—are being retired by providers across the country. To avoid total service interruption, migrating to VoIP (Internet Telephony) is no longer a luxury; it is the new official standard for all business calls.

ComReg has already established the framework for this transition, and we are currently deep in a “gradual phase-out” period moving toward a complete network shutdown.

If your business is still holding onto legacy lines, the time to act is right now.

What is the Current Situation in Ireland?

The copper network is being turned off exchange by exchange. Once fibre broadband becomes available in a specific geographic area, the official countdown clock for the legacy lines in that region begins.

As we move through 2026, the squeeze on old lines is tightening in a few major ways:

• No New Orders: Major Irish infrastructure providers, including eir, have completely stopped taking new orders for ISDN lines. If you have an existing line, it might work for now, but you cannot add new channels or move them to a new office premises.

• Fading Technical Support: Even if your local area hasn’t hit its official shutdown date yet, maintaining these copper lines is becoming increasingly difficult. Reliability is dropping, and wait times for physical repairs from line providers are getting significantly longer.

• Massive Price Hikes: Keeping old technology alive is getting expensive. Many Irish businesses have recently seen their monthly line rental costs jump to a whopping €88 a month. That represents a massive 175% price increase compared to 2024, when those same lines cost just €32 a month.
